heatpump, water rats, duct work (including high velocity), baseboard 

depends on your location, local expends, constructional damage for installation, you may investigate between all these options,

for hot air, you could install regular duct work or might consider high velocity duct work.

you may also consider upfront cost, carrying cost. for water heated solution, be ware of frozen pipe in extreme cold weather since old house normally would have poor insulation.

my 2 cents
